A FIRM.

POCKET-lNHALER.

SPECIFICATION forming part of Letters Patent No. 697,117, dated April 8, 1902.

Application filed September 3, 1901. erial No. 74,082. (No model.)

To all whom, it may concern:

Be it known that I, HARRY J. VALENTINE, a citizen of the United States ofAmerica, and a resident of Hempstead, in the cou nty of Nas San and State of New York, have invented certain new and useful Improvements in Pocket- Inhalers, of which the following is a specification.

This invention relates to pocket-inhalers I0 which are used by persons having pulmonary troubles-such as asthma, hay-fever, and the like-and for catarrh, colds, headache, 850.; and the object of the invention is to provide a convenient, simple, and effective device which may be closed when out of use, so as to prevent the evaporation of the volatile medicinal substance with which the device is charged, and which maybe opened either partially or entirely, so that open partially the inhaler may be applied to the anterior nares v for use and an inflow of medicated vapors caused, and so that when entirely opened the absorbent agent may again be saturated with the medicinal substance.

To these ends myinvention consists of certain features of construction and combinations of parts to be hereinafter described and then claimed.

In the accompanying drawings, Figure 1 is a perspective view showing the inhaler in use. Fig. 2 is a side elevation of the inhaler closed. Fig. 3 is a longitudinal section of the same; and Fig. at is a side elevation of the cartridge, which is provided with the absorbent agent.

\Vith especial reference to the drawings, a indicates a tube or cylindrical casing having at one end a contracted portion or neck Z), forming a nipple for insertion into the anteriornares. Preferably,and,infact,ordinarily,

the casingais made of sheet metal drawn into suitable shape. Received in the larger end of the casing a is a cartridge, which is composed of a central stem 0, having at one end a cylindrical hollow sheet-metal head (1, opening toward the other end of the stem, which end is terminated by a button 6. Adjacent its closed outer end the head dis perforated to furnish an air-inlet hole or holes (1. Around the stem is applied a body of absorbent material, preferably a strip of muslin wound 5o tightly on the same and pushed sufficiently far into the hollow head (1 as to protect it and hold it in position. This absorbent bodyfis saturated with some suitable vaporizable medicinal substance, according to the disease the inhaler is intended for. Preferably the absorbent body should not be pushed so far into the head (Z as to cover the air-inlet.

The cartridge, constructed substantially as described, is pushed into the casing until a rim d formed on the closed end of the head (I, abuts against the end of the tubular casing. The head d snugly fits the casing, but not so tightly as to prevent the sliding of the adjustable cartridge in the casing. Of course the button c is of somewhat less diameter than the interior of the casing, so as to provide an annular air-space around the button atthe base of the nipple. This button serves to retain the absorbent body on the stem 0.

To use the inhaler, the cartridge is pulled out until the air-inlets in the head (1 are exposed, and the inhaler being now held in the hand (see Fig. 1) the nipple is applied to the nose,or rather to the anterior nares thereof. It is preferable to limit the outward movement of the cartridge, and for that purpose the head d is provided with a teat or stud g at one side of its inner end,which may move Within limits defined by the ends of a longitudinal groove or slot h, formed in the larger end of the cars ing. Extending from the outer end of the groove or slot h is an angular groove or slot h, which opens out at the edge of the casing, so that by means of the teatginserted therein a bayonet-joint connect-ion is pro'vided. By simply sliding the cartridge outwardly its movement is limited and the inhaler is in using position, and when in this position the parts may be separated by a partial rotation and outward pull of the cartridge for recharging or any other reason.

WVhat I claim as new is- In an inhaler, the combination with a casing, of a sliding cartridge; one of which has a projection, and the other being provided with a longitudinal groove to allow the car- Signed at Brooklyn, New York, this 27th tridge to have a, limited sliding movement day of August, 1901.

which the groove is provided to allow the ear- O. H. VOORHES, tridge to be removed. S. NELSON LYONS.
